The Given equation is:
2.5(x
- 3) + 1.7x = 10.8(x + 1.5)
Solving the equation means
finding the value of 'x' in this equation.
This can be done
as follows:
Step 1: Open the
brackets
2.5x - 2.5*3 + 1.7x = 10.8x +
10.8*1.5
==> 2.5x - 7.5 + 1.7x = 10.8x +
16.2
Step 2: Transfer all terms of equation containing x to
left hand side and other terms containing only numbers to tight hand side of
equation.
==> 2.5x + 1.7x - 10.8x = 16.2 +
7.5
Please note that when we change the side of any term
its sign gets reversed from + to -, and vice versa.
Step 3:
Add terms on each side of equation.
==> -6.6x =
23.7
Step 4: Divide both side of equation by 6.6. This done
so that the left hand side will become equal to
x.
==> x = 23.7/(-6.6) =
-3.591
